Hi Chris!
Funny you mention those as I am in the process of painting the JJ figure, which, by the way, does NOT look like the painting on the cover, as you may already know.
The plastic is soft and a real treat to work with. However, I do recommend to replace the heads with resin ones. Not that they are bad, but they miss that crispness only resin can give. I replaced mine with a Model Cellar RFC pilot one, topped with a cap from Andrea's BoB pilot.
Hopefully some pics coming up soon...
Ciao
